As Mario with at least 14 power stars,you should see some light coming from the roof,go into first player view (press X) and look into the light.You should have wings on your cap.Press up to dive,press down to come up.There will be a tower in the middle of the course,go onto the tower,Voila!The ? switch is yours!If Mario gets a feather, he will turn into Wing Mario he will be able to fly.If Yoshi gets a power flower,he will spit out fire.If Luigi gets a power flower he will turn transparent,and he'll be able to go through some walls.If Wario gets a power flower,he'll turn into metal and he'll be able to kill enemies by touching them,and he can walk under water.

To get the red ? box, go through the front door of the castle and you will see a light shining in the middle of the floor.Run up to it and look up using the X button AND PRESS THE DOWN BUTTON ON YOUR RIGHT OF THE DS. You should travel to a different land. What you have to do, is jump on the big red button on one of the forts and all the red boxes will become solid. Now Mario can “fly”, Luigi can become “Invisible” Yoshi gets “Firebreath". PLEASE TELL ME IF IT WORKS!

here is how to make ? blocks solid press x then press down right after pressing x. then you will telaport then fly down on to the platform, jump on the switch, run off the platform.go try the bricks! (sometimes bob-oms might come out the bricks)
